Additional Info
The Stellarvue SV115T35 was originally designed to be our best visual and most portable refractor telescope. It delivers visual performance that exceeds that of any other 4" refractor while remaining light weight. With reflector-like color correction and the best contrast, this is the ultimate dream machine for observers. This telescope clearly discerns fine planetary details, splits close double stars, and displays extended regions of nebulosity under dark skies. Spherochromatic correction is as good or better than any current, grab and go, production telescope we sell, excluding the larger SV160R. The photographic performance of this telescope when using an APS or smaller chip is enhanced when used with our SFF7-21 field flattener.
Fully multicoated apochromatic triplet objective: With a 115 mm f-7 apochromatic triplet objective, this telescope provides extremely high contrast, a perfect star test and reflector-like color correction. Lenses are hand figured by a master optician to a high Strehl ratio. This is a no-compromise optic that will perform as well as or better than any lens in its size class. To further enhance this high level of contrast, extreme broadband multicoatings are used on all six lens surfaces, making the stars appear vivid and the background velvet black. These coatings transmit light above and below the visual spectrum, minimizing reflections seen on ccd images. Vic Maris currently uses a 2" focuser version of this telescope (SV115T20) at home, which matches this 3" version in optics and performance. It meets his demand for a no compromise telescope that is easy to carry and use.
Stardust white aluminum tube and dew shield: The aluminum tube and dew shield is painted in a lustrous stardust white finish and has black anodized aluminum fittings. When the telescope is used, this dew shield may be extended to minimize dewing of the objective at night and to serve as a glare shade during the daytime. When being stored, the dew shield retracts to reduce the length of the telescope.
Internal tube treatment: The main tube interior is painted "ultra flat" black inside and is baffled to eliminate excess light reflection. The 11 baffle ridges of the focuser drawtube are painted "ultra flat" black to eliminate the most common type of reflections. This treatment is far better than drawtubes that are merely threaded. The blackened edges of the objective are the final method used to preserve the outstanding contrast of this exceptional apochromatic lens.
3" Feather Touch dual speed focuser: The fully rotating 3" Feather Touch offers 3.5" of travel and is large enough to work with our biggest field flattener. There is no need to ever go larger than this massive 3" focuser. The Feather Touch features an ultra-smooth coarse/fine focus knobs (10:1 Ratio), internal brake system, ultra-low backlash system.
Aluminum hinged rings: The SV115 comes with two hinged, aluminum mounting rings. Each ring has five screws top and bottom. Threaded holes are 6mm. There is one center hole, two holes spaced 1.5" apart and two holes spaced 60 mm apart. You can utilize the optional TP-10 rail for telescope mounts that uses the Vixen style rail or use the optional TP6 for mounts that use the larger Losmandy style rail.
C9S Case: A heavy duty, thickly padded storage case is included. The C9S case is of a higher quality than import hard cases that fall apart after a few uses. Many customers have had a CS9 case for ten or more years and continue to report them as strong as ever.
What else do you need? In addition to the supplied accessories, you will need a star diagonal or erecting prism, eyepiece(s) and amount, and a reflex or optical finder scope
Light gathering and magnification power: The purpose of a telescope is to gather light and magnify the apparent size of the object being viewed. A 115 mm refractor gathers 270 times the amount of light the naked eye can, revealing faint objects in space. Magnification power (the increase in relative size of the object being viewed) is dependant upon the eyepiece being used. Different eyepieces provide different magnification powers. Since this telescope uses a highly accurate, hand figured objective lens triple tested in the USA, these telescopes are free of the coma and astigmatism seen in many import telescopes, providing sharper details when viewing at higher powers. Dawes limit states that the maximum power for telescopes under good conditions is about 270 powers for a 115 mm telescope, but you can exceed ever this power on a clear night. This is a true apo triplet capable of very high power, when conditions permit. Check the Recommended Accessories section to make the best choice for eyepieces.
Two year warranty and Stellarvue Service: Stellarvue telescopes and accessories are covered by a two year warranty. But it does not stop there. Since we are a telescope maker, we can repair your telescope for a nominal fee years after it goes out of warranty, should you accidentally drop it on concrete or otherwise damage it. Buy a Stellarvue Telescope with confidence. Our customer care is legendary.
